Unless you’re doing work in a shop, you probably haven’t needed to buy a ruler in quite some time. And while you might not really be in the market, we can safely say that this is the ruler you should buy if you need one. Since the markings fade from black to white, it can be used on any color surface. So darker surfaces that used to cause your eyes all kinds of pain are now easy to mark and measure on. It will be available in April and is one of those purchases you won’t be too excited about until you need to use it.
